Recommendation of the use of cleaner burning gasoline
■
Cleaner burning gasoline, including reformulated gasoline that contains oxygen-
ates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many
areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated gasoline. These types of gasoline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.
Non-recommendation of the use of blended gasoline
■
Lexus allows the use of oxygenate blended gasoline where the oxygenate con-
●
tent is up to 10% ethanol or 15% MTBE.
If you use gasohol in your vehicle, be sure that it has an octane rating no lower
●
than 87.
Lexus does not recommend the use of gasoline containing methanol.
●
Non-recommendation of the use of gasoline containing MMT
■
Some gasoline contains an octane enhancing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoline that contains MMT. If fuel contain-
ing MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
If your engine knocks
■
Consult your Lexus dealer.
●
You may occasionally notice light knocking for a short time while accelerating
●
or driving uphill. This is normal and there is no need for concern.
